I saw a post somewhere, not sure where, about an excellent odor control idea that did not require ventilation. All I remember about it is that it used a bucket and the bucket is drilled I think and you place it in the corner of your grow space and it filters out odor very well. Not alot to go on for finding that topic and I'm not sure if I saw it on GC or not, but hopefully someone knows what I'm talking about
Update: I think I found the thread, this idea looks killer http://forum.grasscity.com/do-yourself/728452-diy-ona-odor-control-bucket-cheap-easy.html
Does pumping your plant's air supply full of foreign terpenoids not effect the taste/smell come harvest?
